I'm trying to use pnotes to pass error message.
Here is the module where the error case is supposed to happen:

sub handler : method    {
    my ($self, $r) = @_;
...
    $self->{r}->pnotes(error => 'Darn');
    return Apache2::Const::SERVER_ERROR;
}
...
1;

Now the special error handler:

sub handler    {
    my $r = shift;

    $r->content_type('text/html');
    $r->print($r->pnotes("error"));
    return Apache2::Const::OK;
}
1;

And finally httpd.conf part to connect it all:

...
ErrorDocument 500 /error
...
PerlModule dir_browse::error
<Location /error>
  SetHandler perl-script
  PerlResponseHandler dir_browse::error
</Location>

The problem is that pnotes('error') does not keep its value when redirected to error handler (i tried to redirect explicitly using headers_out->set(Location => ...) and Apache2::Const::REDIRECT but the result was the same).
Now, I've read in pnotes doc that "The values get reset automatically at the end of each HTTP request". Does that mean, that in my case the request is finished before getting to error handler? Or there is some other issue?

Thanks,
Artem.
